By far the largest use of nitrogen gas within this industry sector is for laser cutting. Laser cutting with nitrogen is intended for applications where oxidation is not wanted. Nitrogen does not react with the material and is therefore the predominant cutting gas for high-alloyed steels, including stainless steel.
Nitrogen gas is used as an ‘assist gas’ to prevent oxidisation or discolouration and to blow away the molten material from the cut edge. It is also used in certain types of laser cutting machine as a ‘purge gas’ to ensure the laser beam guide path from the resonator (where the beam is generated), to the cutting head, is free of contamination that could otherwise affect the power or alter the shape of the beam.
When using nitrogen any oxidation is avoided and it is the basis for preserving the corrosion resistance of laser-cut stainless steel components and for good paint adhesion on laser cut mild steel samples. By cutting high-alloy steels with laser cutting nitrogen, you can ensure a burr-free, clear cut surface that can be processed further straight away.
Eliminating the expense, inconvenience, hazardous handling, and storage problems associated with the transportation of high pressure nitrogen cylinders. With PSA technology they are the most efficient and dependable generators available today. Fully automatic, they require no supervision for operation.
